how long would it take before all the humans and animals used up all the oxygen in the atmosphere, and we all died?

Algae produces from 73-87% of the oxygen on earth. It wouldn't completely destroy all life.

If all the plants died, we would have about 100 years worth of oxygen in the atmosphere.
Remember, the atmosphere is huge.
This does happen, thankfully not regularly, and not totally.
It almost happened 65 million years ago when a meteorite hit the earth and caused wildfires.
The fires burnt most of the vegetation. There was a lot of dust in the atmosphere that blocked out the sun and a lot of the algae died.
Luckily, seeds survived as did some algae. Then its just a case of reproducing.

Actually, most oxygen comes from the sea, it is produced by cyanobacteria mostly, along with algae. So, we wouldn't die. If oxygen were reduced dramatically, we would adapt to the new conditions slowly, since it wouldn't happen all of a sudden.

We wouldn't, oxygen comes from many sources, algae for instance produces masses of it.

that would take some cataclysmic event for that to happen lol....but you're forgetting how oxygen became so abundant on our earth in the first place...or so theory suggests anyway
I'm curious as to why you are asking?
